What Is a Tax Investigation by HMRC?

Updated: Feb 11, 2023

A tax investigation by the HM Revenue and Customs (HMRC) in the United Kingdom is an inquiry into an individual or a company's tax affairs. The purpose of the investigation is to determine if there has been any non-compliance with the tax laws and to ensure that the taxpayer has paid the correct amount of tax.


What Is a Tax Investigation by HMRC?


The HMRC has the power to investigate tax evasion for a period of up to 20 years. The investigation may be triggered by a variety of factors, including a tip-off from a member of the public, information received from other government agencies, or a discrepancy in the taxpayer's records.


Once the HMRC begins a tax investigation, it will gather information from a variety of sources, including banks, building societies, credit reference agencies, and other government agencies. The HMRC will also request information from the taxpayer, including records of their income, expenses, and assets.


It is important to note that the taxpayer has a legal obligation to cooperate with the HMRC during a tax investigation. This means that the taxpayer must provide the HMRC with all the information that they request in a timely manner.


The HMRC will then analyze the information gathered to determine if there has been any non-compliance with the tax laws. If the HMRC finds evidence of tax evasion, it may choose to take civil or criminal action. If the case is civil, the HMRC will try to negotiate a settlement with the taxpayer. If the case is criminal, the HMRC will prosecute the taxpayer and the case will be heard in court.


It is important to note that the HMRC has the power to impose penalties for non-compliance with tax laws. If the taxpayer is found to have evaded tax, they may be required to pay the tax owed, plus interest and penalties. In some cases, the HMRC may also confiscate assets, such as property or vehicles.


So we can say that a tax investigation by the HM Revenue and Customs in the United Kingdom is an inquiry into an individual or a company's tax affairs to determine if there has been any non-compliance with the tax laws. The investigation may be triggered by a variety of factors and the taxpayer has a legal obligation to cooperate with the HMRC during the investigation. If the HMRC finds evidence of tax evasion, it may take civil or criminal action and impose penalties for non-compliance with the tax laws.


What Triggers a Tax Investigation?

A tax investigation by the HM Revenue and Customs (HMRC) in the United Kingdom can be triggered by a variety of factors. The purpose of the investigation is to determine if there has been any non-compliance with the tax laws and to ensure that the taxpayer has paid the correct amount of tax.


One common trigger for a tax investigation is a tip-off from a member of the public or another government agency. The HMRC has a hotline for people to report suspected tax evasion, and they receive thousands of tip-offs each year.


Another trigger for a tax investigation is a discrepancy in the taxpayer's records. The HMRC uses sophisticated computer systems to detect discrepancies in the records of taxpayers. For example, if the taxpayer's reported income does not match the information that the HMRC has received from other sources, this may trigger an investigation.


In some cases, a tax investigation may also be triggered by the taxpayer's lifestyle. If the taxpayer's lifestyle appears to be inconsistent with their reported income, this may raise suspicions of tax evasion. For example, if the taxpayer has a large, expensive home or drives an expensive car, but their reported income does not match this level of wealth, this may trigger an investigation.


Another trigger for a tax investigation is an unusual pattern of transactions. If the taxpayer has a large number of transactions in a short period of time, this may raise suspicions of tax evasion. For example, if the taxpayer has a large number of cash transactions or a high volume of bank transfers, this may trigger an investigation.


It is also worth noting that the HMRC has the power to conduct random audits of taxpayers. This means that a taxpayer may be selected for investigation even if there is no specific trigger for the investigation.


Thus a tax investigation by the HM Revenue and Customs in the United Kingdom can be triggered by a variety of factors, including tip-offs from a member of the public or another government agency, discrepancies in the taxpayer's records, an inconsistent lifestyle, an unusual pattern of transactions, or a random audit. The purpose of the investigation is to determine if there has been any non-compliance with the tax laws and to ensure that the taxpayer has paid the correct amount of tax.


How Do HMRC Investigate Tax Evasion in The UK?

The HM Revenue and Customs (HMRC) is responsible for investigating tax evasion in the United Kingdom. Tax evasion is a criminal offense and is considered a serious matter by the HMRC.


There are several methods that the HMRC uses to investigate tax evasion in the UK.


  1. Data Analysis: The HMRC uses data analysis tools to identify patterns of tax evasion. They compare tax returns against other financial data, such as bank statements and credit card transactions, to identify discrepancies.

  2. Whistleblowers: The HMRC encourages whistleblowers to come forward with information about tax evasion. They offer anonymity and protection to those who provide information that leads to a successful prosecution.

  3. Taskforces: The HMRC operates taskforces to target specific areas of tax evasion, such as the construction industry or the gig economy. These task forces bring together a team of specialist HMRC officers who use intelligence, data analysis, and targeted visits to businesses to identify tax evaders.

  4. Undercover Operations: In some cases, the HMRC may carry out undercover operations to gather evidence of tax evasion. These operations are only carried out in exceptional circumstances and only after careful consideration of all other options.

  5. Inquiries: The HMRC has the power to make inquiries into an individual’s tax affairs. This may involve the examination of financial records, the questioning of witnesses, and the collection of evidence. The HMRC may also ask for additional information, such as bank statements, credit card records, and receipts.


If the HMRC finds evidence of tax evasion, it will take action to recover the evaded taxes. This may involve a criminal investigation and prosecution, or it may result in a civil settlement. If a criminal prosecution is pursued, the tax evader may face a fine, imprisonment, or both.


It is important to note that the HMRC takes tax evasion very seriously and will use all available methods to investigate and prosecute those who engage in this criminal activity. The HMRC also has a range of powers to recover taxes owed, including the seizure of assets, the imposition of a tax charge, and the issue of a notice to collect tax owed.


How Far Back Can a Tax Investigation by HMRC Go


How Far Back Can a Tax Investigation by HMRC Go?

In the United Kingdom, the HM Revenue and Customs (HMRC) has the power to investigate tax evasion for a period of up to 20 years. This period is known as the "investigation window" and applies to all types of taxes, including income tax, corporation tax, capital gains tax, and value-added tax (VAT).


The 20-year investigation window is a general rule, but there are certain circumstances where the HMRC may be able to go further back. For example, if the tax evader has deliberately concealed or destroyed records, the investigation window may be extended. Additionally, if the tax evader has used a scheme to evade tax, the HMRC may be able to go back as far as the date that the scheme was put in place.


The HMRC can also investigate tax evasion beyond the 20-year investigation window if there is evidence of fraud. In such cases, there is no limit to the amount of time that the HMRC can go back to investigate.


It is important to note that the HMRC has the power to investigate tax evasion even if the taxpayer has not been informed of the investigation. This means that the HMRC can start an investigation at any time, regardless of how long ago the tax was evaded.


The HMRC also has the power to share information with other agencies, such as the National Crime Agency (NCA), if there is evidence of tax evasion that may also constitute a criminal offense. This means that the NCA may also be able to investigate tax evasion beyond the 20-year investigation window if there is evidence of fraud.


The general rule is that the HMRC can investigate tax evasion for a period of up to 20 years, although there are certain circumstances where this may be extended. It is important to note that the HMRC can start an investigation at any time and that there is no limit to the amount of time that they can go back if there is evidence of fraud. Taxpayers should be aware that the HMRC has the power to investigate and prosecute tax evasion, even if the evasion took place many years ago.


How Long a Tax Investigation by HMRC Can Take?

The length of a tax investigation by the HM Revenue and Customs (HMRC) in the United Kingdom can vary depending on the complexity of the case. However, the average length of a tax investigation is between 12 and 24 months.


The length of the investigation is influenced by several factors, including the size of the tax evaded, the complexity of the case, the number of individuals and companies involved, and the level of cooperation from the taxpayer. If the taxpayer cooperates with the HMRC and provides all the required information in a timely manner, the investigation may be resolved more quickly.


In some cases, the investigation may take longer if the HMRC requires additional information or if there is a dispute over the amount of tax owed. If the HMRC has to gather evidence from other sources, such as banks, this may also increase the length of the investigation.


It is also important to note that the length of the investigation may be influenced by the number of other investigations that the HMRC is currently working on. If the HMRC is dealing with a large number of complex cases, this may result in a longer wait for a resolution.


The length of the investigation is also affected by the outcome of the investigation. If the HMRC finds evidence of tax evasion, it may choose to take civil or criminal action. If the case is civil, the HMRC will try to negotiate a settlement with the taxpayer. If the case is criminal, the HMRC will prosecute the taxpayer and the case will be heard in court. The length of a criminal case can vary greatly, depending on the complexity of the case and the length of the trial.


It is also important to note that if the taxpayer decides to appeal a decision made by the HMRC, this can also extend the length of the investigation.


Thus the length of a tax investigation by the HMRC in the United Kingdom can vary depending on several factors, including the complexity of the case, the level of cooperation from the taxpayer, and the number of other investigations that the HMRC is currently working on. On average, a tax investigation takes between 12 and 24 months to resolve, but this can be longer if the case is complex, if there is a dispute over the amount of tax owed, or if the taxpayer decides to appeal the decision.


Should We Get Tax Investigation Insurance


Should We Get Tax Investigation Insurance?

Tax investigation insurance is a type of insurance policy that is designed to cover the costs of a tax investigation by the HM Revenue and Customs (HMRC) in the United Kingdom. The policy provides financial support to help cover the costs of professional fees, such as legal and accountancy fees, that may be incurred during an investigation.


So, should you get tax investigation insurance in the UK? The answer is that it depends on your individual circumstances. Here are some factors to consider:


  • Your Risk of Being Investigated: Tax investigation insurance is primarily designed for people who are at a higher risk of being investigated by the HMRC. This might include self-employed individuals, small business owners, and those with complicated financial affairs. If you are not in a high-risk category, then you may not need this type of insurance.

  • The Cost of an Investigation: Tax investigations can be very expensive, especially if you need to hire professional help. Tax investigation insurance can help to cover these costs and provide peace of mind.

  • The Cost of the Insurance: Tax investigation insurance can be expensive, and the cost of the policy will depend on various factors, such as your level of coverage and the extent of your financial affairs. You should carefully consider the cost of the insurance and whether it is worth it in your particular case.

  • Your Level of Risk Tolerance: Some people may prefer to take their chances and not have insurance, while others may prefer to have the security of knowing that they are covered if they are investigated. It is important to consider your personal level of risk tolerance and make a decision based on this.

  • The Strength of Your Records: A tax investigation can be much easier to deal with if you have strong records that support your financial affairs. If you have good records, you may feel more comfortable without insurance, as you will be better prepared to defend yourself if you are investigated.


So whether you should get tax investigation insurance in the UK depends on your individual circumstances. You should consider your risk of being investigated, the cost of an investigation, the cost of the insurance, your level of risk tolerance, and the strength of your records. Ultimately, it is up to you to make an informed decision based on your particular situation.


What are the Different Types of Tax Investigations by HMRC?


HMRC can conduct different types of Tax Investigations. Here is a list of the most popular types of tax investigations:


What are COP8 Investigations

COP8 investigations refer to tax investigations carried out under Code of Practice 8 by HM Revenue and Customs (HMRC) in the UK. These investigations are initiated when HMRC receives information or has reason to suspect that a taxpayer has engaged in tax avoidance or tax planning that is considered to be abusive or contrived. The investigation process involves a review of the taxpayer's financial and tax affairs and may result in the imposition of penalties and the recovery of any unpaid tax.


COP9 Investigations start when HMRC in the UK

COP9 investigations refer to tax investigations carried out under Code of Practice 9 by HM Revenue and Customs (HMRC) in the UK. These investigations are initiated when a taxpayer comes forward to disclose that they have engaged in tax avoidance or tax planning that is considered to be abusive or contrived. The disclosure must be made voluntarily and must be full and complete. If the disclosure meets the required criteria, HMRC may offer the taxpayer a contract under the terms of the Code of Practice 9, which provides assurance that HMRC will not seek criminal prosecution in relation to the disclosed matters. The taxpayer will, however, still be required to pay any tax due, interest, and penalties.


VAT Investigations

VAT investigations by HM Revenue and Customs (HMRC) in the UK are carried out to ensure that businesses are complying with their Value Added Tax (VAT) obligations. VAT is a tax on sales made by businesses in the UK and is chargeable on most goods and services. VAT investigations may be triggered by a variety of factors, including errors or discrepancies in a business's VAT returns, concerns about VAT fraud or evasion, or intelligence received from other sources.


During a VAT investigation, HMRC may carry out a range of activities, including reviewing a business's records, conducting interviews with the business's representatives, and making site visits to check records and other documentation. HMRC may also issue assessments for any unpaid VAT, interest, and penalties.


Compliance Checks Investigations

Compliance checks investigations by HM Revenue and Customs (HMRC) in the UK are carried out to ensure that taxpayers, including individuals and businesses, are complying with their tax obligations. Compliance checks may be conducted on a random basis or may be triggered by specific concerns or risks identified by HMRC.


During a compliance check, HMRC may request information and documents from the taxpayer, such as tax returns, bank statements, and invoices. HMRC may also conduct interviews with the taxpayer or their representatives, either over the phone or in person. The purpose of these checks is to verify that taxpayer has calculated their tax liabilities correctly and has maintained accurate records.


If HMRC identifies any errors or discrepancies during a compliance check, they may take further action, such as issuing assessments for additional tax, interest, and penalties. However, if the taxpayer has made a genuine mistake, they may be able to correct this and avoid further penalties by cooperating with HMRC and making any necessary adjustments to their tax affairs.


Desk-based Review Investigations

Desk-based review investigations by HM Revenue and Customs (HMRC) in the UK are a type of tax investigation that involves the review of a taxpayer's records and tax returns without a site visit. These reviews are often conducted to identify any errors or discrepancies in the taxpayer's tax affairs, and they may be triggered by specific concerns or risks identified by HMRC.


During a desk-based review, HMRC will request information and documents from the taxpayer, such as tax returns, bank statements, and invoices. HMRC may also use data analytics and other tools to review the taxpayer's records and identify any anomalies or areas of concern. The purpose of the review is to verify that taxpayer has calculated their tax liabilities correctly and has maintained accurate records.


If HMRC identifies any errors or discrepancies during a desk-based review, they may take further action, such as issuing assessments for additional tax, interest, and penalties. However, if the taxpayer has made a genuine mistake, they may be able to correct this and avoid further penalties by cooperating with HMRC and making any necessary adjustments to their tax affairs.


Civil Evasion Investigations

Civil evasion investigations by HM Revenue and Customs (HMRC) in the UK are carried out when HMRC suspects that a taxpayer has deliberately evaded tax. Tax evasion is a criminal offense, but civil evasion investigations are conducted as a civil matter, rather than a criminal matter. The purpose of a civil evasion investigation is to recover any tax that has been evaded and to impose penalties and interest charges.


During a civil evasion investigation, HMRC may use a range of powers to obtain information and evidence, including the power to issue information notices, carry out inspections and seize documents, and interview taxpayers and their representatives. The investigation will be conducted by specialist investigators within HMRC, who will look for evidence of deliberate evasions, such as failing to declare income, claiming false expenses, or using offshore accounts to conceal income or assets.


If HMRC identifies evidence of civil tax evasion, they may seek to recover any tax that has been evaded, as well as impose penalties and interest charges. The penalties can be significant and may be up to 100% of the tax due, depending on the seriousness of the evasion.


"PAYE" Investigations by HMRC

PAYE (Pay As You Earn) investigations by HM Revenue and Customs (HMRC) in the UK are carried out to ensure that employers are complying with their obligations to deduct and pay income tax and National Insurance contributions (NICs) from their employees' pay. PAYE is the system used to collect income tax and NICs from employees' salaries, and employers are responsible for operating the system correctly.


During a PAYE investigation, HMRC may review an employer's records and payroll systems, and may carry out interviews with the employer's representatives. HMRC may be looking for errors or discrepancies in the calculation and payment of income tax and NICs, such as failure to deduct the correct amount, misclassification of workers, or failure to account for expenses and benefits.


If HMRC identifies any errors or discrepancies during a PAYE investigation, they may take further action, such as issuing assessments for additional tax, interest, and penalties. The penalties for non-compliance can be significant and may be up to 100% of the tax and NICs due, depending on the seriousness of the breach.


Contractor Tax Investigations by HMRC

Contractor tax investigations by HM Revenue and Customs (HMRC) in the UK are carried out to ensure that contractors and their clients are complying with their obligations under the IR35 rules. IR35 is a set of rules designed to prevent tax avoidance by individuals who work as contractors, but who might be considered to be employees for tax purposes.


During a contractor tax investigation, HMRC may review the contracts and working arrangements between the contractor and their client, as well as the contractor's records and tax returns. HMRC may be looking for evidence that the contractor is actually an employee, and therefore subject to income tax and National Insurance contributions (NICs) in the same way as employees.


If HMRC identifies evidence that the contractor is an employee, they may seek to recover any income tax and NICs that have not been paid, as well as impose penalties and interest charges. The penalties can be significant and may be up to 100% of the tax and NICs due, depending on the seriousness of the breach.


"Tax Credit Benefit Fraud" Investigations by HMRC

Tax Credit Benefit Fraud investigations by HM Revenue and Customs (HMRC) in the UK are carried out when there is suspicion that a claimant has provided false or misleading information in order to receive tax credits to which they are not entitled. Tax credits are a form of financial support provided by the government to help families with children or those on low incomes.
